My invention consists in new and useful improvements in agauge cock forboilers and the like and has for its object to provide a device fordetermining the water level in boilers, and equipped with a novel,elongated, cylindrical sealing bar whereby a maximum number of renewableseatsmay be had for sealing the nipple of the gauge cock.

Heretofore, with gauge cocks employing 1o sealing devices ofconventional form, considerable trouble had been experienced fromcorrosion due to bad water in the boiler,

sealing device to a new seat. With my improved structure, no matter howbadly the device has become corroded, the sealing member is soconstructed that it may be readily loosened by the use of a small punchand a light tap on the end of the sealing bar, when it is desired toproduce a new seat.

A still further object of the invention resides in the simplicity andefficiency of the structure and economy-of manufacture and installation.

With the above and other objects in view' which will appear as thedescription proceeds, my invention consists in the novel features hereinset forth, illustrated in the accompanying drawing, and moreparticularly 7 pointed out in the appended claims.

Referring to the drawings in which numerals of like character designatesimilar parts throughout the several views,

Figure 1 is a top plan viewof the device.

Figure 2 is a view in side elevation with the ported plug shown insection to illus-.

trate the relative position of the sealing bar in sealing position, andv I Figure 3 is a perspective view of the sealin bar removed from thedevice.

in the drawings, 1 designates the plug member, preferably "composed ofbrass or other suitable metal, threaded at one end 2 to facilitate itsapplication to a boiler head. 3. represents an upwardly projecting lug,integral with the plug 1 and havinga transverse aperture 4 at its upperextremity, adapted to register with correspondingapertures 5 providedtransversely in the bifurcated end 6 of an extension or arm 7, integralopposite the threads 2.

withthe weighted lever or handle 8. The eX- ten'sion or lug 3-ismaintained in pivotalengagement with the arm 7 I by means of a bolt orcotter pin 9 which projects through. the apertures 4 and 5. I Q I Theplug 1 is provided withthe conventional longitudinally extending port'or pas sage 10;located centrally thereof and terminating in' thereduced nipple 11' atzthe end Atithe junction of the extension provide atransversely extending preferably horizontal support 12, recessed toreceive an elongated cylindrical sealing bar 13, preferably composed ofrelatively soft material V 7 mas weighted handle 8, adjacent the nipple11, I which often makes it diflicult to change the to form aseat-at'any'point of engagement 7 on its periphery by the nipple 11; Thesup;

port 12: completely encircles thebar' 13 as at 1 1, on at least onesideof the extension 7 and ls tapped, preferably in itsiupper wall toreceive setscrew '15, whereby the sealing bar 13 is iretainedin place.The .face of the support 12 immediately adjacent the ni-pple, '11is'apertured as at 16 toipermit said nipple V to extendtherethroug-h,'for. engagement with the periphery of the sealing-ba'r13.; Thea-function and operation of my improvedgauge cock isobvious. 'When 'the weigh-tedj 'handle Sis raised,-the extension 7swings on the pivot 9 causing the sealingbar 13 to disengage the nipple11, thus freeing the'pa'ssage 10 and permitting the vescape: of steamorfluidtherefrom. Whenthe handle 8 is released, its weightcauses thesealing/bar K 13 toi again engage the nipple 11, the latter seatingitself on the'periphery ofthe-lbar 13,

through the aperture 16. 5 e c Y 'When" any one seat becomes iworn fromcontinued use, thethumb screw-15 is uhscrewed and the cylindrical bar-1-3 I either moved longitudinally in the transverse 'supiport l2 orrotated about its own axisto-proe vide anew seat, when the thumb. :screwis again-tightened to retain the bar inj'plac'e. v It will thus be'seenthatfwith my improved, sealingibar,ia maximuminumber of seats maybe obtained by simply aslight change in posi I tion of the bar, withoutremoving the same from its support. In fact practically every ion c"a:support'member-carried by-said handle transversely of said aperturedplug, a-longi tudinally adjustable, elongated substantially point on theperiphery of the bar 13 may be used as a seatfor the nipple 11, beforethe said bar is discarded for a new one.

From the foregoing it is believed that my invention may be readilyunderstood by those skilled-in the art-without further description, itbeing borne in mind that-numerous changes may be made in the details ofconstruction without departing from the spirit of the invention as SQtfOI'th in the following claims; What I claim and desire to securebyLetters Patent is 1. A gauge cock for boiler heads an'dthe like,including an apertured-pl-ug, a handle pivoted to said plug, and alongitudinally a'djustable, elongated substantially cylindrical sealing:.barmounted -onsaid handle :tra-nsversely of said apertured-plugforsealing raid aperture. j

2. In a gauge cock including an apertured plugha'vingagdischa'rgenozzle, an-elongated sealing bar, of; substantially soft-material, cylindrical in-cross section and located transversely of;said discharge, nozzle,'and-means whereby substantially the entireperiphery ofsaid sealing bar may be successively presented' to saiddischarge nozzle to providea maximum number seats.

3. Axgauge cock: including an apertured plug, a weighted handlepivotedto said plug,

cylindrical sealing bar carried in said sup port andadapted to-engagethe discharge end of said plug at any point-on itsperiphery.

4. A gauge cock including ,aported; plug terminating at one end inaldischarge nozzle, a weighted handle pivoted tosaid plug, a sup:

port carried? by said handle transversely of said discharge nozzle andencircling the periphery of an elongated. substantially cylindricalsealing bar, a reduced opening in the wall of said support adjacent saiddischarge nozzle whereby the latter may extend through said wall toengage r'thez periphery of :said

I sealing bar.

l 5. A zgau gecocklincluding a portedmplug terminating at one endi-in'adischa'rgemozzle,

a weighted'handle .pivoted to saidpl-ug, a
